• "A.1.2 Reference Frame – Global Domain – Surface Area Equivalence" substituido por "Reference Frame – National Domain – Surface Area Equivalence"
  To verify Domain completeness, with an initial discrete national grid whose area is defined as equal to the surface area of the DNGS Reference Frame’s National model.

• "A.1.3 Reference Frame – Global Domain – Cell Boundary Overlap" substituido por "Reference Frame – National Domain – Cell Boundary Overlap"
  To verify Location uniqueness, with an initial discrete national grid defined without any overlapping DNGS Cells.

• "A.1.4 Reference Frame – Tessellation Sequence" ... To verify a DNGS Reference Frame’s definition comprises a sequence of discrete national grid tessellations with progressively finer resolution that can support data at multiple levels of spatial resolution.

• "A.1.5 ..." ... "Reference Frame — National Area Preservation". To verify for DNGS cells in each successive level of grid refinement, that Domain completeness and Position uniqueness are preserved, with total area of those DNGS cells the same as the initial global grid and no overlapping DNGS cells.

• "Reference Frame — Cell Shape"... To verify that all of the cells of a DNGS specification have shapes that are simple polygons on the surface model of the Nation; where, the boundary of the DNGS Cell is non-self-intersecting.
